Once you have notified the police, you absolutely DO NOT want the police to arrive to you having a firearm in your hand. Once you have verified there is no longer a threat, holster your weapon, if it's a rifle, put it on the ground. DO not worry about taking the magazine out just put it on the ground in a safe place that is AWAY from you. When the police show up, put your hands up, show them you are not a threat and tell them “He/they broke into my house, I was in fear for my life, I discharged my firearm and neutralized the threat. Before I say more, I need to talk to my attorney”
THIS is why I have Carry Insurance through the USCCA. ONE call and I’ve got a high powered 2A lawyer in my corner.
the biggest thing is that the police are going to be coming to what they are told is a shooting. they are NOT always going to get the information you give to 911, so you MUST assume that they will be showing up not knowing what happened. Comply with whatever they tell you to do untill they can determine that you are the victim. IF they come in and see you standing over the perp with a gun in your hand, they are going to assume that YOU are the assailant and could very well shoot you. (yes, it has happened on many occasions the police showed up only to shoot the wrong person. Make sure though that you ONLY tell them as much as they need to determine that you are not a threat “Officer, this man broke down my door, I came down and was in fear for my life, so I used my weapon to neutralize the threat. I cannot say any more untill I talk with my lawyer.
the problem is that when the police show up, and you start talking anything you say can be twisted, or forgotten….or worse yet, you could say something in the heat of the moment, then once your mind has cleared you remember it differently….changing your story makes you look less credible.
